## 1.2 Facility Description The Inver Hills Generating Plant is a peak electrical gene ration facility with a capacity of 440 megawatts (MW). The facility is composed of six identical pre- NSPS General Electric natural gas or fuel oil-fired simple cycle combustion turbine/generator sets. The facility is on call to operate, as needed, any or all of the six primary turbine/generator sets. Each turbin e is capable of using natural gas and distillate oil as a fuel source. Natural gas is the primary fuel, and fu el oil is used mostly during curtailment of natural gas (which is typically in the winter unless a natural gas pipeline break occurs during non-winter months). The Permittee has indicated that historically the overall fuel usage for the turbines is 90 percent natural gas and 10 percent fuel oil. There are also two emergency generators powered by diesel engines and several insignificant emission sour ces on site. Distillate oil and other petroleum products are stored in a 10 million gallon above ground storage tanks.

## 1.6 Changes to Permit

· Updates to reflect current MPCA templates and standard citat ion formatting;

· Emission calculations were updated to now include CO 2 

## e;

· Removed State Implementation Plan (SIP) limits that were te rminated on the date the USEPA approved the revision to the SIP;

· Residual fuel oil has been removed as an allowable fuel ty pe in accordance with the revised SIP;

· Changed permit language so requirements are more clearly applied to each unit individually within a group;

· Two previously insignificant activities are now subject to NESHAP Subpart ZZZZ are now included as emission units. The substation black start diesel gene rator is now EU 009, and the fire pump diesel engine is now EU 010. These emission units ma ke up the newly created GP 005;

· New unit exemption language for the acid rain program has been updated in both the permit and the appendix;

· Modeling parameters have been moved from the permit to the appendix;

· Removed stacks/vents from groups.

· Tank 002 (TK002) and Tank 003 (TK003) have been remove d from the permit. The tanks were emptied, cleaned, and isolated from fuel delivery. Only the structures remain on site.

· Inlet fogging system is currently in-operable, and there are no plans to restore the system in the foreseeable future, so the requirements for operating w ith inlet foggers have been removed from the permit.

1.7 Changes to the State Implementation Plan The Pine Bend area surrounding Xcel’s Inver Hills fac ility currently meets all National and Minnesota Ambient Air Quality Standards (NAAQS and MAAQS). At one time, however, the area’s ambient air exceeded the sulfur dioxide (SO 2 

## ) NAAQS. In response, the MPCA crafted conditions des igned to bring the area into attainment with the standards. Those conditio ns applied to this and other facilities

### Technical Support Document, Permit Action Number: 03700 015-004

Page 3 of 11 

## determined to be responsible for the ambient air quali ty problems. The MPCA is required to have a plan to maintain compliance with the NAAQS. Conditions in th e permit identified as “Title I Condition: SIP for SO2 NAAQS ” are elements of this maintenance plan.

During the reissuance of the Part 70 operating permit f or its Inver Hills Generating Plant, Xcel Energy has requested that the MPCA change limits that are included in Minnesota’s State Implementation Plan to maintain the Pine Bend area (the area surrounding the Inve r Hills Generating Plant) as an attainment (maintenance) area for sulfur dioxide (SO 2 

## ).

The requested changes are summarized in Table 5.

Table 5. Changes to the SIP Conditions
Permit Limitation or Condition Description of Change Effect

Sulfur content of fuel The maximum allowable fuel sulfur

content to be changed from 0.48 percent by weight to 0. 005 percent by weight. The maximum sulfur content of the fuel currently being provided to the facility is 0.0015 percent by weight so the lowered limit should have no effect. Fuel Oil Analysis Method A of demonstrating compliance t o be changed from 0.48 percent by weight to 0.005 percent by weight. Method B to be changed from 0.10 percent by weight to 0.0015 percent by weight. This has been done to reflect the lower sulfur content of fuel oil. As long as the fuel oil contains less than
0. 0015 percent sulfur by weight, the facility will be able to use a less onerous compliance option.



## This request is the result of a cooperative effort by Xcel Energy, Flint Hills Resources, and the MPCA. At its Inver Hills facility, Xcel receives Ultra Low Sulfu r Diesel from the nearby Flint Hills refinery that is guaranteed to have a maximum sulfur content of 15 ppmw (0.0015% by weight). This sulfur content is much lower than the limit in the permit (0.48% by we ight), so Xcel Energy has requested that the limit be lowered to more appropriately reflect the actual sulfu r content of the fuel. The new conditions are more conservative than those contained in the previous permit, and (following their approval by EPA) they will continue to assure that compliance with the SO 2 

## NAAQS is maintained, and to help accommodate anticipated construction in the Pine Bend area.

Minnesota must incorporate these changes into its SIP afte r which EPA must approve them. For this reason, the conditions that are to be eliminated incl ude language indicating that they are no longer applicable only after EPA approves the change.

2. Regulatory and/or Statutory Basis

New Source Review The facility is an existing major source under New Sou rce Review regulations. No changes are authorized by this permit.

### Technical Support Document, Permit Action Number: 03700 015-004

Page 4 of 11 

## Part 70 Permit Program The facility is a major source under the Part 70 permit p rogram.

New Source Performance Standards (NSPS) The Permittee has stated that no New Source Performance Standards apply to the operations at this facility. National Emission Standards for Hazardous Air Pollutants ( NESHAP) The facility exceeds the 10 tpy and 25 tpy emission thr esholds for single and total HAPS, so the facility is a major source of HAPS.

The combustion turbines are affected sources subject to 40 CFR 63 Subpart YYYY. However, they are existing stationary combustion turbines, and therefore h ave no applicable requirements from this NESHAP (see 40 CFR Section 63.6095).

GP 002 contains two emergency diesel generators (EU 00 7 and EU 008) that do not need to meet the requirements of the NESHAP Subpart ZZZZ because the gen erators are >500 hp, and are not contractually obligated to be available for more than 15 hou rs per calendar year in accordance with 40 CFR §63.6590(b)(3)(iii).

GP 005 contains a fire pump diesel engine (EU 009) an d a substation black start diesel generator (EU 010) that are subject to the same requirements of NESHA P Subpart ZZZZ because the units are both classified as emergency compression ignition RICE, that are <500 hp, and located at a major source of
HAP emissions.

Compliance Assurance Monitoring (CAM) None of the units at the facility are subject to CAM bec ause there is no control equipment.

Acid Rain Program The facility has two post-1990 Caterpillar emergency di esel-fired reciprocating internal combustion engines that are grid connected and therefore subject to Title IV. The Permittee committed to limiting diesel fuel sulfur content to 0.05 percent by weight in these units and applied for a new unit exemption from EPA’s Acid Rain progra m.

Clean Air Interstate Rule (CAIR) / Transport Rule (TR) NO X 

## Annual Trading Program [also known as the Cross-State Air Pollution Rule (CSAPR)] Xcel Energy

–

Inver Hills Generating Plant was subject to CAIR when it was initially promulgated. However, several actions have taken place resulting in CA IR no longer being an applicable requirement:

· November 3, 2009

–

Applicability of CAIR was stayed in Minnesota as of Decemb er 3, 2009, except as described in 40 CFR § 52.1240(b). (40 CFR §§ 51.123(a)(3), 51.124(a)(2), 51.125(a)(3), 52.35(e))

· August 8, 2011

–

40 CFR §§ 52.1240(c) and 52.1241(c) were promulgated, replacing CAIR with TR/CSAPR.

· December 30, 2011

– Applicability of TR/CSAPR was stayed by the United States Court of Appeals, and EPA was ordered to go back to CAIR.

## as NO 2 

## allowances are held by Minnesota sources, as allowances hav e been deducted for program termination. The stay of CAIR in Minnesota continu es to be in effect and therefore, no CAIR or CSAPR applicable requirements remain for this facility, at this time.

Minnesota State Rules Portions of the facility are subject to Minn. R. 7011.2 300 (Standards of Performance for Stationary Internal Combustion Engines).

TK 001 (Distillate Oil Tank) is not subject to Minn. R. 7011.1505 (Standards of Performance for Storage Vessels) because the vapor pressure of fuel oil falls b elow the 128 mm Hg (2.5 psia) threshold. The highest vapor pressure identified in the application for distillate fuel oil no. 2 fuel oil has a vapor pressure of about 6 mm Hg (0.115 psia). TK 001 is subj ect to Minn. R. 7011.0715 (Standards of Performance for Post-1969 Industrial process Equipment) as the tank began operation in 1972.

## 3. Technical Information This section discusses a number of technical and regulato ry decisions that were made during the review of the application and during permit drafting.

3.1 Calculations of Potential to Emit Attachment 1 to this TSD contains Form GI-07, which summ arizes the PTE of the Facility, while Attachment 2 contains detailed spreadsheets and supporting in formation prepared by the MPCA and the Permittee.

On January 1 st 

## , 2014 new Green House Warming Potentials (GWP) for Met hane and Nitrous Oxide went into effect. These new GWPs have been taken into acc ount and included in the emissions calculations for CO 2 

## e.

3.2 Monitoring In accordance with the Clean Air Act, it is the responsibi lity of the owner or operator of a facility to have sufficient knowledge of the facility to certify that the facility is in compliance with all applicable requirements.

In evaluating the monitoring included in the permit, t he MPCA considered the following:

· the likelihood of the facility violating the applicable requirements;

· whether add-on controls are necessary to meet the emis sion limits;

· the variability of emissions over time;

· the type of monitoring, process, maintenance, or cont rol equipment data already available for the emission unit;

· the technical and economic feasibility of possible per iodic monitoring methods; and

· the kind of monitoring found on similar units elsewhe re.

· Table 7 summarizes the monitoring requirements.

Limit The fuel oil supplier must provide a certification or

other record that the sulfur content of the fuel oil meets the limit. The facility currently receives fuel that is guaranteed to have a maximum sulfur content of 0.0015 percent by weight. This is well bel ow the required limit so an exceedance is unlikely. The supplier guarantee can be found in Attachment 4 of this TSD.

The amount of fuel used at the facility must be tracked daily. The sulfur content of each shipment of fuel oil used at the facility must be analyzed upon receipt. On a monthly basis, the facility determinates compliance with the fuel usage limit. Sulfur dioxide emission rates are also calculated from these data.

SO 2 

### ≤ 0.50 lbs/MMBtu

(Minn. R. 7011.2300) None It is unlikely that the opacity limit will be exceeded due to the decreased particle formation from the low sulfur content of fuel used.

3.3 Insignificant Activities Xcel Energy - Inver Hills Generating Pit has several ope rations which are classified as insignificant
activities under the MPCA’s permitting rules . These are listed in Appendix B to the permit.

Table 8. Insignificant Activities

Insignificant Activity General Applicable Emission limit Discussion Fuel use: space heaters fueled by propane, less than 420,000 Btu/hr PM ≤ 0.6 or 0.4 lb/MMBtu, depending on year constructed Opacity ≤ 20% with exceptions (Minn. R. 7011.0510/0515) For this unit, based on the fuels used and EPA published emissions factors, it is highly unlikely t hat it could violate the applicable requireme nt. In addition, these types of units are typically operated and vented inside a building, so testing for PM or opacity is not feasible.

Indirect heating equipment with a capacity less than 420,000 Btu/hour, etc. PM ≤ 0.6 or 0.4, depending on year

constru cted Opacity ≤ 20% with exceptions (Minn. R. 7011.0510/0515) For these units, based on the fuels used and EPA published emissions factors, it is highly unlikely t hat they could violate the applicable requirements.

R. 7011.0710/0715) For these units, based on EPA published emissions factors, it is highly unlikely that they could violate the applicable requirement. In addition, these units are typically operated and vented inside a building, so testing for PM or opacity is not feasible. Individual units with potential emissions less than 2000 lb/year of certain pollutants PM, variable depending on airflow Opacity ≤ 20% (with exceptions) (Minn. R. 7011.0715 and
Min n. R. 7011.0610)

or SO 2 

### ≤ 0.5 lb/MMBtu Opacity ≤ 20% (Minn. R. 7011.2300) The facility contains temporary engines for various compressors and pumps as well as internal combustion engines burning distillate oil, gasoline, or natural gas. There are also VOC fugitive emissions from solvents (parts washers no longer use solvents), and from pumps, valves, and flanges on the distillate oil forwarding system/loading rack. Due to the limited use and size of the engines ( <250 hp) it is unlikely that these units will exceed the requirements. Infrequent use of spray paint equipment for routine housekeeping or plant upkeep activities not associated with primary production processes at the stationary source PM, variable depending on airflow or process weight rate Opacity ≤ 20% (Minn. R. 7011.0715) While spray equipment will have the potential to emit particulate matter, these particular activities are those not associated with production, so they would be infrequent and usually occur outdoors. Testing or monitoring is not feasible.

Various small fuel oil tanks that do not have a tankage capacity of more than 10,000 gallons There are no standards of performance promulgated in this part for storage vessels with a storage capacity of 2,000 gallons or less.

(Minn. R. 7011.1505) Based on the capacity of the tanks and total throughput, it is highly unlikely that they could violate the applicable requirement or that testing would be feasible.



## 3.4 Permit Organization In general, the permit meets the MPCA Delta Guidance fo r ordering and grouping of requirements. The permit conditions are placed at the group level. Group 001 includes the six electric generating combustion turbines (six emission units). Group 002 includes the two emergency diesel generators.

In addition, there are two appendices to the permit. (Appendix A is reserved for the Operator’s Summary which is not used with this permit.) Appendix B contains a listing of the Insignificant Activities at the facility. Appendix C records the New Unit Exemp tions from the requirements of the Acid Rain program for Emission Units EU007 and EU008 (See 40 CFR § 72.7 for more information), and Appendix C contains the modeling parameters associated with the st acks for each of the electric generating combustion turbines (i.e., the stacks for the members of Group 1.)

PERMIT SHIELD:

Subject to the limitations in Minn. R. 7007.1800, c ompliance with the conditions of this permit shall be deemed compliance with the specific provision of th e applicable requirement identified in the permit a s the basis of each condition. Subject to the limita tions of Minn.

## FACILITY DESCRIPTION:

Xcel Energy’s Inver Hills Generating Plant is a pea k electrical generation facility with a capacity of 440 megawatts. The facility is on call to operate, as needed, any or all of six identical pre-NSPS Genera l Electric primary turbine/generator sets. Each turb ine is capable of using natural gas, distillate oil , or residual oil as a fuel source. Historically, natur al gas has been the primary fuel source. Fuel oil is most frequently used during curtailment of the natural g as supply. The turbines commenced operation prior to November 15, 1990; thus, they are not subject to Ti tle IV of the Clean Air Act (the Acid Rain Provisions).

The Inver Hills Generating Plant also has two post- 1990 Caterpillar emergency diesel-fired reciprocati ng internal combustion engine generators. The Permitt ee has applied for a new unit exemption and agreed to limit diesel fuel sulfur content to 0.05 percent by weight.

Another activity at the site is the storage of dist illate oil and other petroleum products in ten mill iongallon above-ground storage tanks. There are also several insignificant sources.

PER 003

Air Emission Permit No. 03700015-003 is the reissua nce of the Part 70 permit for the Xcel Energy – Inv er Hills Generating Plant. It supersedes Air Emission Permit No. 03700015-002. The permit does not auth orize any new construction or physical modifications, alt hough some changes have been made to the permit primarily to facilitate changes to SIP.

The SIP conditions in the permit ensure that the ai r quality in the area around the Inver Hills Genera ting Plant (the Pine Bend area) remain in compliance wit h the National Ambient Air Quality Standards (NAAQS) for sulfur dioxide. This permit streamline s the facility’s SIP requirements. In doing so, th e permit becomes more restrictive (i.e., more protect ive of the NAAQS). The Title I SIP conditions in t he permit will be submitted to the EPA for its approva l of the changes to the SIP.

A small number of housekeeping changes have also be en made in this permit.

## TECHNICAL SUPPORT DOCUMENT For AIR EMISSION PERMIT NO. 03700015-003

This Technical Support Document (TSD) is intended for all p arties interested in the permit and to meet the requirements that have been set forth by the fed eral and state regulations (40 CFR § 70.7(a)(5) and Minn. R. 7007.0850, subp. 1). The purpose of this document is to provide the legal and factual justification for each applicable requi rement or policy decision considered in the preliminary determination to issue the draft/propose d permit.

1.2. Description of the Permit Action

The Inver Hills Generating Plant is a peak electrical gener ation facility with a capacity of 440 megawatts (MW). The facility is composed of six identical p re-NSPS General Electric natural gas or fuel oil-fired simple cycle combustion turbine/gener ator sets. The facility is on call to operate, as needed, any or all of the six primary turbine/ge nerator sets. Each turbine is capable of using natural gas, distillate oil, or residual oil as a fuel source. Natural gas is the primary fuel, and fuel oil is used mostly during curtailment of natural gas ( which is almost always a winter phenomena, unless a natural gas pipeline break occurs dur ing non-winter months). The Permittee has indicated that historically the overall fuel usage for the turbines is 90 percent natural gas and 10 percent fuel oil. There are also two emerg ency generators powered by diesel engines and several insignificant emission sources on site . Distillate oil and other petroleum products are stored in three 10 million gallon above ground s torage tanks.

The turbines are not subject to Title IV because they commen ced operation before November 15, 1990, (§72.6(b)(1)). The facility also has two post-1990 Caterpillar emergency diesel-fired reciprocating internal combustion engines that are grid connected and therefore subject to Title IV. The Permittee committed to limiting die sel fuel sulfur content to 0.05 percent by weight in these units and applied for a new unit ex emption from EPA’s Acid Rain
program.

**Page 2 of 23 Date: 1/16/2007**  

## Due to the low level of public interest in this facility (asc ertained by the low levels of complaints received by the MPCA about the facility and the facility’s r elatively low emissions), no Community Involvement Team was convened to educate the pub lic about the reissuance of the Part 70 permit.

1.3 Description of any Changes Allowed with this Permit Issu ance
The permit application submitted by Xcel Energy (“Xcel”) contained no new physical changes or changes in the method of operation at the facility. The fac ility, however, proposed changes to some of the State Implementation Plan (SIP) conditions in th e permit.

The Pine Bend area surrounding Xcel’s Inver Hills facility c urrently meets all National and Minnesota Ambient Air Quality Standards (NAAQS and MAAQS). At one time, however, the area’s ambient air exceeded the sulfur dioxide (SO 2 

## ) NAAQS. In response, the MPCA crafted conditions designed to bring the area into attainment with the standards. Those conditions applied to this and other facilities determined to be respo nsible for the ambient air quality problems. The MPCA is required to have a plan to maintain com pliance with the NAAQS. Conditions in the permit identified as “Title I Condition : State Implementation Plan (SIP) for SO2 NAAQS” are elements of this maintenance plan.

This permit prepares for the simplification of condition s in Minnesota’s SO 2 

## SIP. The company proposes to forego some flexibility allowed under the prev ious permit for this simplification. The new conditions are more conservative than those containe d in the previous permit, as (following their approval by EPA) they will impose lower su lfur fuel content limits; reduce the number of allowable fuels; eliminate alternative means of d emonstrating compliance; and remove alternative recordkeeping requirements. A new comp liance method is added, allowing the company to avoid certain analyses if fuel with a much lower sulfur content is used.

Minnesota must incorporate these changes into its SIP after w hich EPA must approve them. For this reason, the conditions that are to be eliminated inclu de language indicating that they are no longer applicable only after EPA approves the change.

A detailed analysis of the changes to the permit and the rati onale for making those changes is provided in Attachment 4.

## 2. Regulatory and/or Statutory Basis

New Source Review The facility is an existing major source under New Source Re view regulations. (Potential emission of PM, PM 10 

## , and SO 2 

## exceed the 250 tpy threshold, as do potential and actual emissions of NO X 

## .) No physical changes or changes in the method of operatio n are authorized by this permit. Part 70 Permit Program The facility is a major source under the Part 70 permit prog ram. (The potential of the facility to emit PM 10 

## , SO 2 

## and NO X 

## exceeds the 100 tpy threshold. In addition, the facility’s e missions exceed the 10 tpy and 25 tpy thresholds for single and total Ha zardous Air Pollutants (HAPs). New Source Performance Standards (NSPS) There are no New Source Performance Standards applicable t o the operations at this facility. National Emission Standards for Hazardous Air Pollutants ( NESHAP) The facility’s emissions exceed the 10 tpy and 25 tpy thresho lds for single and total HAPs, so the facility is a major HAP source. The combustion turbines are a ffected sources subject to 40 CFR 63 Subpart YYYY. Since, however, they are existing stationa ry combustion turbines, there are no applicable requirements for them in this NESHAP. (See 40 CFR § 63.6095.) Compliance Assurance Monitoring (CAM) None of the units at the facility are subject to CAM because t hey have no control equipment.

Minnesota State Rules Portions of the facility are subject to Minn. R. 7011.2300 (S tandards of Performance for Stationary Internal Combustion Engines). The distillate oil tanks associated with the facility are no t subject to Minn. R. 7011.1505 (Standards of Performance for Storage Vessels) since the va por pressure of the oil falls below 128 mm Hg (2.5 psia). (The highest vapor pressure identifi ed in the application for distillate fuel oil no. 2 fuel oil has a vapor pressure of about 6 mm Hg (0.115 psia).)

3. Technical Information

This section discusses a number of technical and regulator y decisions that were made during the review of the application and during permit drafting.

3.1 Calculations of Potential to Emit

Xcel submitted emission calculations that were reviewed an d corrected. The most recent version of AP-42 was the source of criteria pollutant and Hazardou s Air Pollutant emission factors for the six combustion turbines and the two diesel generators. V olatile organic emissions from the tanks were calculated using the TANKS 4.0 program.

Attachment 1 to this TSD contains Form GI-07, which summariz es the PTE of the Facility, while Attachment 2 contains detailed spreadsheets and supportin g information prepared by the MPCA and the Permittee.

3.2 Periodic Monitoring

In accordance with the Clean Air Act, it is the responsibilit y of the owner or operator of a facility to have sufficient knowledge of the facility to certify that the facility is in compliance with all applicable requirements.

### Technical Support Document, Permit Action Number: 03700015-003

**Page 7 of 23 Date: 1/16/2007**  

## In evaluating the monitoring included in the permit, the MP CA considers the following:

x The likelihood of violating the applicable requirements;

x Whether add-on controls are necessary to meet the emission li mits;

x The variability of emissions over time;

x The type of monitoring, process, maintenance, or control e quipment data already available for the emission unit;

x The technical and economic feasibility of possible perio dic monitoring methods; and

x The kind of monitoring found on similar units elsewhere. Table 4 summarizes the periodic monitoring requirements f or those emission units for which the monitoring required by the applicable requirement is none xistent or inadequate.

be tracked daily. The sulfur content of each shipment of fuel oil used at the facility must be analyzed upon receipt. On a monthly basis, the facility determinates compliance with the fuel usage limit. Sulfur dioxide emission rates are also calculated from these data.

This level of monitoring is appropriate due to the low level of SO 2 

## emissions at the facility and the low concentration of sulfur in the oil relative to the limit.

Restriction / Sulfur Dioxide Limit The amount of fuel used at the facility must

be tracked daily. The fuel oil supplier must provide a certification or other record that the sulfur content of the fuel oil meets the limit. On a monthly basis, the facility determinates compliance with the fuel usage limit. Sulfur dioxide emission rates are also calculated from these data.

This level of monitoring meets the standard of reasonable precision, reliability, accessibility, and timeliness required by the regulation.

GP004 Minn. R.

7011.0715 None The Industrial Process Equipment rule applies as a default since no other standard applies. The tanks are not expected to generate particulate matter or opacity.

3.3 Insignificant Activities

Xcel Energy’s Inver Hills Generating Plant has several oper ations that are identified as insignificant activities. These activities have no applic able requirements and have no associated periodic monitoring requirements. They are listed in Appen dix B to the permit.

### Technical Support Document, Permit Action Number: 03700015-003

**Page 9 of 23 Date: 1/16/2007**  

## 3.4 Modeling Submittal

Xcel was required to submit dispersion modeling informatio n for PM 10 

## and NO X 

## for this facility by November 23, 2003. Xcel fulfilled this requirement. The requirement has been removed from the permit.

3.5 “Additional” Emission Units

Three existing tanks were previously considered insignif icant activities but are now identified as emission units. Their emissions are now calculated to excee d one ton of VOCs per year, which exceeds the threshold for insignificant activities. They h ave been added to Delta so that their emissions will be quantified and reported; however, there are no applicable conditions for the tanks, so there are no permit conditions addressing these t anks.

3.6 Permit Organization

In general, the permit meets the MPCA Delta Guidance for ord ering and grouping of requirements. The permit conditions are placed at the gro up level. Group 1 includes the six electric generating combustion turbines (six emission uni ts). Group 2 includes the two emergency diesel generators. Group 3 consists of the stacks for each of the electric generating combustion turbines (i.e., the stacks for the members of Gro up 1.)

## In addition, there are two appendices to the permit. (Appen dix A is reserved for the Operator’s Summary which is not used with this permit.) Appendix B cont ains a listing of the Insignificant Activities at the facility. Appendix C records the New Unit Exemptions from the requirements of the Acid Rain program for Emission Units EU007 and EU008. (See 40 CFR § 72.7 for more information.)

3.7 Comments Received

The Public Notice Period began on September 8, 2006 and end ed October 9, 2006. No comments were received from the public during the public n otice period.

The EPA 45-day Review Period began on September 8, 2006 and e nded October 23, 2006. No comments were received from the public during the public n otice period. During this period, discussions were held with EPA reviewers for the State Imple mentation Plan (SIP). (These reviewers were interested in the permit because it contai ns conditions identified as a “Title I Condition: State Implementation Plan (SIP) for SO2 NAAQS” that will be incorporated into Minnesota’s SIP.) These discussions identified some misun derstandings between the MPCA and EPA Region 5. The misunderstandings were clarified without any changes to the permit.

3.8 Post-Public Notice Permit Changes

During the public comment period, MPCA staff noticed that a SIP condition (i.e., a condition identified as a “Title I Condition: State Implementation Pl an (SIP) for SO2 NAAQS”) requiring a Quarterly Report was a submittal/action requirement and, therefore, part of Table B of the permit. Since Table B contains no citations, EPA had not iden tified this condition as part of the SIP. To ensure that this requirement would be included in th e SIP when EPA modified Minnesota’s Plan, a permit condition was added basically duplicating this submittal/action requirement so that it would appear with the appropriate cit ation in Table A. (The new condition can be found under the Reporting heading of the Facility sec tion.)

No additional public comment period or EPA review was need ed since the condition reiterates an existing condition. A reference to this change has also b een added to the “Summary of Changes to SIP Conditions” in Attachment 4.

4. Conclusion

Based on the information provided by Xcel Energy, the MPCA has reasonable assurance that the proposed operation of the emission facility, as described i n the Air Emission Permit No. 03700015-003 and this technical support document, will no t cause or contribute to a violation of applicable federal regulations and Minnesota Rules.

# Attachment 4 to the Technical Support Document

for Permit Action Number 03700015-003 Changes to the SIP Conditions

In the application for a renewal of the Part 70 operating perm it for its Inver Hills Generating Plant, Xcel Energy requested that the MPCA change a number of conditions that are included in Minnesota’s State Implementation Plan (SIP) to maintain th e Pine Bend area (the area surrounding the Inver Hills Generating Plant) as an attainm ent (maintenance) area for sulfur dioxide (SO 2 

## ). 2



## There have been two very significant changes since the Stat e Implementation Plan (SIP) for the Inver Hills Generating Station was first prepared. First, the Pine Bend area is now in attainment with the National Ambient Air Quality Standards (NAAQS) fo r SO 2 

## . (This continues to be demonstrated, most recently in the ambient air quality model ing included with the July 18, 2006 SIP submittal from the Minnesota Pollution Control Agency t o Region 5 of the U.S. Environmental Protection Agency. That submittal includes changes to the SIP proposed by Flint Hills Resources, LP for its Rosemount refinery.) Second, lo w-sulfur fuels are commonly produced and are widely available.

At its Inver Hills facility, Xcel receives a shipment of low- sulfur fuel oil by pipeline roughly every other year. Fuel analysis reports reviewed in 2006 ind icate that the sulfur content of the delivered fuel ranges between 0.01 and 0.03 percent sulf ur by weight (0.01 - 0.03 wt percent).

The MPCA agreed to make some of the changes requested by Xcel . In addition, the MPCA initiated changes to clarify the SIP conditions. 3 

## The changes to the SIP conditions continue to assure that compliance with the SO 2 

## NAAQS is maintained.

The permit reflects the following changes to the SIP that we re proposed for facility’s combustion turbines:

Sulfur dioxide limit. The maximum allowable sulfur dioxide emission rate will be c hanged from 0.67 pounds per million BTU to 0.50 pounds per million BT U. This lower emission rate is

**2** 

### The MPCA submitted the Title I SIP conditions in **Air Emission Permit No. 03700015-001 to the US Environmental Protection Agency in August 2002. EPA re**  **viewed and approved those Title I SIP conditions as of July 2, 2004. (See 69 FR 31891.) The approval of**  **those SIP conditions represents the most recent action on the SIP conditions for this fac**  **ility.**

**3** 

### Air Emission Permit No. 03700015-001 (and, subseq **uently, 03700015-002) included an alternative Fuel Supplier Certification for GP 001 (Electric Generating Combustio**  **n Turbines) identified as an ”Alternative to SIP monitoring for the Fuel Oil Ana**  **lysis and SO 2**  

### Emission Rate calculation.” However, **this condition was not identified as a Title I Conditio n for the SIP. Since it lacked this identification**  **, the MPCA did not believe it was approved by US EPA into t**  **he SIP in its July 2, 2004 action. To provide a less onerous fuel certification process protectiv**  **e of the SO 2**  

### NAAQS, the MPCA is **proposing an alternative method of fuel oil analysis that, upon approval by US EPA, will become a part**  **of the SO 2**  

### SIP for the Inver Hills Generating Plant.

### Technical Support Document, Permit Action Number: 03700015-003

**Page 20 of 23 Date: 1/16/2007**  

## already allowed as an alternative to the existing limit. How ever, the higher maximum emission rate will be eliminated from the permit after the SIP chang e is approved by EPA.

Allowable fuels. The SIP conditions in the permit currently allow the combus tion of natural gas, distillate oil, and residual oil. Residual oil will be remo ved as an allowable fuel. The remaining fuels are currently allowed by the permit, but the fuel li kely to have the highest sulfur content – residual oil – will not be able to be burned after EPA appr oves the SIP changes.

Fuel oil sulfur content. The permit’s SIP conditions currently allow a fuel oil sulf ur content of 0.64 percent by weight. The proposed permit would reduc e the maximum allowable fuel sulfur content to 0.48 percent by weight (after EPA’s approval). A maximum fuel sulfur content of 0.48 wt percent effectively limits the emissions of sulfur dioxide below 0.50 lb/MMBtu, as shown below:

### Note: Heating values for No. 2 distillate oil rang **e from 19429 Btu/lb to 19701 Btu/lb. Use of the lower end of the range is the more conservative option.** 



## Thus, compliance with the 0.50 lb SO 2 

## /MMBtu limit is demonstrated by compliance with the fuel sulfur content limit of 0.48 percent by weight

.
Fuel oil analysis. 

## The SIP conditions in the current permit provide two options for Xcel to demonstrate compliance with the fuel sulfur limit. The first is by obtaining a fuel oil certification indicating that each shipment meets t he allowed limits. While fuel oil suppliers may have routinely provided certifications when the SIP was originally developed for the Pine Bend area, fuel certification are no longer availab le from these suppliers. (In their place, the fuel supplier will provide a guarantee that shipments wi ll meet a fuel oil specification.) Because of this, the first option described above – acquiring a certification on each shipment – is no longer a feasible alternative. This option will be eliminat ed from the SIP and the permit.

The alternative compliance method in the SIP (and th e permit) allows the facility to perform an analysis for sulfur content in the fuel oil, includ ing the testing of the fuel oil in the fuel line to the gas turbines in January and in July. Since the Inv er Hills facility now receives low-sulfur fuel oil (less than 0.05 percent sulfur by weight), these co nditions are overly rigorous. In particular, there are difficulties in obtaining fuel oil certif ications for each individual shipment, and the sampling and testing of the fuel oil in the fuel li nes seems exceptionally burdensome. (The facility’s supplier guarantees that the sulfur cont ent of the fuel oil will not exceed 0.05 percent by weight. A copy of this guarantee is presented at the end of this attachment.)

### Technical Support Document, Permit Action Number: 03700015-003

**Page 21 of 23 Date: 1/16/2007**  

## Because of this, an additional method of compliance has been proposed. The first requirement of this new option would be for Xcel to obtain an assu rance from its fuel suppliers that the oil it receives would contain less than 0.10 percent sulfu r by weight. This certification would not be required for each shipment but could be a “blanket” guarantee for anticipated (future) deliveries, such as the one included with the TSD. The fuel su pplier would be required to notify Xcel of exceptional events (i.e., when the delivered oil ex ceeded the 0.10 percent threshold). In those cases, the new option would not be available and Xc el would need to comply with the remaining option from the existing SIP and permit.

The second requirement of this new compliance option would be for Xcel to sample and analyze the fuel oil when it is delivered. Again, a 0.10 weig ht percent sulfur threshold would be used. (Again, if the sulfur content of the fuel oil, as s ampled and analyzed by Xcel, exceeds 0.10 percent, Xcel would need to comply with the other op tion.)

Since the fuel oil used in the combustion turbines is transported to the facility by pipeline, the facility would sample the incoming fuel oil as it is pumped into the storage tanks. Independent samples would be taken at the beginning, middle and e nd of the shipment, with each sample analyzed so that compliance with the fuel oil sulfur limits could be demonstrated with each sample.

Because the threshold of 0.10 weight percent is bel ow the proposed threshold of 0.48 weight percent by a factor of nearly five, this new option provides sufficient assurance that the SO 2 

## NAAQS will continue to be attained.

Permit Limitation or Condition Description of Change Effect



## Sulfur dioxide limit The maximum allowable sulfur dioxide emission rate will be changed from 0.67 pounds per million BTU to 0.50 pounds per million BTU. The new, lower emission rate is already allowed as an alternative to the existing limit. However, the maximum emission rate will be reduced. Limitation on types of fuels burned Residual oil will be eliminated as an allowable fuel. The remaining fuels are currently allowed by the permit, but the fuel likely to have the highest sulfur content can no longer be burned. Sulfur content of fuel The maximum allowable fuel sulfur content will be changed from 0.64 percent by weight to 0.48 percent by weight. The lower sulfur content is already allowed. However, the maximum fuel sulfur content will be reduced.

**Page 22 of 23 Date: 1/16/2007**  

## Permit Limitation or Condition Description of Change Effect



## Fuel Oil Analysis The compliance option that relies on a fuel supplier’s certification will be eliminated. Fuel oil suppliers no longer certify sulfur content on each fuel shipment, so this option has not recently been used. There is no real effect from its elimination. Fuel Oil Analysis A different method of demonstrating compliance with the fuel sulfur content limit will be added. As long as the fuel oil contains less than 0.10 percent sulfur by weight, the company will be able to use a less onerous compliance option. Fuel Supplier Certification The new condition provides an option to keep a guarantee or a certification from the fuel supplier on hand instead requiring a certification. This supports the new method of demonstrating compliance with the fuel sulfur limit. That method requires a guarantee from the fuel supplier rather than a certification. SO 2 

## Emission Rate calculation The description of how to calculate the emissions rate will be removed. None. The calculation above ensures that compliance with the fuel sulfur content of 0.48 percent by weight cannot lead to an exceedance of the 0.50 lb SO 2 

## per million BTU limit. SO 2 

## and Emissions and Operating Records The requirement to retain records related to fuel oil sampling and analyses performed by the company will be removed. Existing conditions requiring that records related to retaining fuel oil supplier’s certifications for five years will be kept in the permit.

Quarterly Reporting requirement A condition was added mirroring the language of a submittal/action condition already in the permit. No new requirements were added. The new condition will appear in Table A of the permit with a citation that identifies it as a “Title I Condition: State Implementation Plan (SIP) for SO2 NAAQS.”

## Minnesota Pollution Control Agency Environmental Analysis and Outcomes Division Public Notice of Proposed State Implementation Plan Revision

NOTICE IS HEREBY GIVEN that the Commissioner of the Minnesota Pollution Contr ol Agency (MPCA) has determined that the State Implementation Plan (SIP) cond itions for Flint Hills Resources LLC’s Pine Bend Refinery (FHR) located at 13775 Clark Road, Rosemount, Dakota County, Minn esota and Northern States Power Company’s Xcel Energy

– Inver Hills Generating Plant (Inver Hills) located at 3185 117 th 

## Street East, Inver Grove Heights, Dakota County, Minnesota should be amended. Both facilities are locate d in the Rosemount/Pine Bend area of the Twin Cities S ulfur Dioxide (SO 2 

## ) maintenance area for the three-hour, 24-hour, and annual SO 2 

## National Ambient Air Quality Standards (NAAQS).

FHR is currently subject to an Administrative Order (Order ) containing Title I requirements which are included in Minnesota’s SIP and were found necessary to demonstrate compliance with the NA AQS for SO 2 

## . Air Emission Permit No. 03700011-012 incorporates Title I requirements for FHR that are currently included in the Order. Under its Title I authority, the MPCA is revising the SIP conditions and will be formally requesting that the U.S. Environmen tal Protection Agency (EPA) amend Minnesota’s SIP to replace the Order and its requi rements with the Title I SIP conditions specified in Air Emission Permit No. 03700011-012, which will serve as a joint Title I SIP/Title V document. Thes e Title I conditions do not expire. This SIP revision is in being conduc ted in conjunction with the issuance of Air Emission P ermit No. 03700011-012. This permit was placed on public notic e on December 23, 2014 until January 21, 2015. The permit and related documentation can be found on the MPCA’s website at http://www.pca.state.mn.us/yrwc6a9 , listed under Tuesday, December 23, 2014 (on the Archived Public No tices page after January 21, 2015). After its issuance , the permit will be submitted to EPA for inclusion into Minneso ta’s SIP to replace the Order. Until the time that the E PA accepts Permit No. 03700011-012 into the SIP, the Order is in full effect and FHR must comply with all aspects of it . Once EPA approves Permit No. 03700011-012 into the SIP, the MPCA will revoke the Order and the joint Title I/Title V pe rmit will become the applicable enforcement document.

Inver Hills’ permit incorporates Title I requiremen ts which are included in Minnesota’s SIP and were found necessary to demonstrate compliance with the NAAQS for SO 2 

## . Title I conditions in Inver Hill’s Air Emission Permit No.
03700015- 003 are already included in Minnesota’s SIP. Under its Title I authority, the MPCA is revising the SIP conditions for this facility and will be formally requesting that the EPA amend Minne sota’s SIP to incl ude the new and revised Title I SIP conditions in Inver Hill’s Air Emissions Permit No. 03700015-004, which will serve as a joint Title I SIP/Title V document. These Title I conditions do not expire. Permit No. 03700015-004 was placed on public notice from June 2, 2014 to July 1, 2014 and the MPCA subsequently issued the permit which is the enforceable document fo r Inver Hills. The permit can be viewed on the MPCA’s websi te at http://www.pca.state.mn.us/index.php/viewdocument.html?gid=21400

.
The proposed SIP revision is now available for public comment.

Background. Title I of the Clean Air Act delegates to the states th e authority to manage an air quality program and requires attainment of the NAAQS as promulgated by the EPA. Both the FHR facility and the Inver Hills facil ity are located in the Rosemount/Pine Bend area of the Twin Cit ies SO 2 

## maintenance area for the three-hour, 24-hour, and annual SO 2 

## NAAQS. A maintenance area is an area which at one time fai led to meet one or more NAAQS, but is now in compliance and has an EPA-approved plan for continued attain ment. Both FHR and Inver Hills are subject to facilit yspecific Title I SIP conditions to ensure continued attain ment of the SO 2 

## NAAQS.

Purpose of the SIP revision. This SIP revision is intended to incorporate new and revised Title I conditions for FHR, replace the existing Order, and incorporate all Ti tle I SIP conditions into Permit No. 03700011-012, w hich will serve as a joint Title I/Title V document. The primary purpos e of this SIP revision is to add a new process to enab le the removal and recovery of more sulfur from fuel produce d at the refinery. This new process will allow FHR to produce gasoline that meets the EPA’s Tier 3 gasoline sulfur stan dard, which is designed to improve ambient air quality. Changes to FHR’s SIP conditions that are included in Permit No. 03700011-012 as propose d are as follows:

## · Installation of a new process to convert gas-containing sulfur and nitrogen into a stable, non-hazardous,

aqueous liquid fertilizer, ammonium thiosulfate (ATS), which will result in a new SO 2 

## emission point.

· Changes to the fuel gas sulfur monitoring requiremen ts for the 45 unit mix drum to add direct monitoring o f fuel gas total sulfur as an additional monitoring option to th e current requirement to monitor at a representative stack for sulfur dioxide emissions. Remove outdated re quirements for monitoring H 2 

## S.

· Incorporate new, more restrictive language reflecting F HR’s current flaring policy, which allows for flaring on ly in the event of malfunction.

· Assorted updates that serve to clarify the requirements of the Order by removing completed requirements and placeholders.

This SIP revision also incorporates revised Title I requ irements for Inver Hills, held in Permit No. 03700015 -004 which serves as a joint Title I/Title V document, into Minne sota’s SIP. The changes to Inver Hill’s SIP conditions ar e as follows:

· Residual fuel oil has been removed as an allowable fuel ty pe in accordance with the revised SIP.

· Removed SIP limits that were terminated on the date tha t EPA approved the revision to the previous SIP.

There are no SIP-relevant construction changes being made to the Inver Hills facility and therefore this proposed SIP revision does not authorize any new operations or emiss ion units at that facility.

Air dispersion modeling has been conducted to verif y that the changes proposed in this notice will not have an adverse impact on compliance with the NAAQS for SO 2

# Minnesota Rules: 

# Amendments and Additions

NOTICE: How to Follow State Agency Rulemaking in th e State Register
The State Register is the official source, and only complete listing, for all state agency rulemaking in its various stag es. State agencies are required to publish notice of the ir rulemaking action in the State Register . Published every Monday, the State Register makes it easy to follow and participate in the important rulemaking process. Approximately 80 sta te agencies have the authority to issue rules. Each agency is assigned specif ic Minnesota Rule chapter numbers. Every odd-numbered year the Minnesota Rules are published. Supplements are published to u pdate this set of rules. Generally speaking, propos ed and adopted exempt rules do not appear in this set because of their short-term nature, but are published in the State Register

.
An agency must first solicit Comments on Planned Rules or Comments on Planned Rule Amendments from the public on the subject matter of a possible rulemaking proposal under active consideration within the age ncy ( Minnesota Statutes §§ 14.101). It does this by publishing a notice in the State Register at least 60 days before publication of a notice to adopt or a notice of hearing, or within 60 days of the effective date of any new statutory grant of required rulemaking.

When rules are first drafted, state agenc ies publish them as Proposed Rules, along with a notice of hearing, or a notice of inte nt to adopt rules without a hearing in the case o f noncontroversial rules. This notice asks for comm ent on the rules as proposed. Proposed emergency rules, and withdrawn propos ed rules, are also published in the State Register . After proposed rules have gone through the comment period, and have been rewr itten into their final form, they again appear in t he State Register as Adopted Rules. These final adopted rules are not printed in t heir entirety, but only the changes made since thei r publication as Proposed Rules. To see the full rule, as adopted and in effect, a per son simply needs two issues of the State Register , the issue the rule appeared in as proposed, and later as adopted.

The State Register features partial and cumulative listings of rules i n this section on the following schedule: issues #1 -13 inclusive; issues #14-25 inclusive (issue #26 cumulative for issues #1-26); issues #27-38 inclusive (issue # 39, cumulative for issues #1-39); issues #40-52 inclusive, with final index (#1-52, or 53 in some years). An annual subject matter index f or rules was separately printed usually in August, but starting with Volume 19 now app ears in the final issue of each volume. For copies or subscriptions to the State Register, contact Minnesota’s Bookstore, 660 Olive Stree t (one block east of I-35E and one block north of U niversity Ave), St. Paul, MN 55155, phone: (612) 297-3000, or toll-free 1- 800-657-3757.

# Minnesota Pollution Control Agency (MPCA) Environmental Analysis and Outcomes Division Public Notice of Proposed State Implementation Plan Revision

NOTICE IS HEREBY GIVEN that the Commissioner of the Minnesota Pollution Contro l Agency (MPCA) has determined that the State Implementation Plan (SIP) conditions for Flint Hill s Resources LLC’s Pine Bend Refinery (FHR) located at 137 75 Clark Road, Rosemount, Dakota County, Minnesota and Northern States Power Company’s Xcel Energy – Inver Hills Generating Plant (Inver Hills)
located at 3185 - 117 th 

### Street East, Inver Grove Heights, Dakota County, M innesota should be amended. Both facilities are lo cated in the
Rosemount/Pine Bend area of the Twin Cities Sulfur Dioxide (SO 2 

### ) maintenance area for the three-hour, 24-hour, and annual SO 2 

### National Ambient Air Quality Standards (NAAQS).

FHR is currently subject to an Administrative Order ( Order) containing Title I requirements which are inclu ded in Minnesota’s SIP and were found necessary to demonstrate compliance with th e NAAQS for SO 2 

### . Air Emission Permit No. 03700011-012 incorporates Title I requirements for FHR that are currently included in the Order. Under its Title I authority, the MPC A is revising the SIP conditions and will be formally requesting that the U.S. Environmental Protection Agency (EPA) amend Minnesota’s SIP to replace the Order and its requirements with the Title I SIP conditions specified in Ai r Emission Permit No. 03700011-012, which will serve as a joint Title I SIP/
Title V document. These Title I conditions do not ex pire. This SIP revision is in being conducted in conju nction with the issuance of Air Emission Permit No. 03700011-012. This permit was placed on public notice on December 23, 2014 until January 21, 2015. The permit
and related documentation can be found on the MPCA’s w ebsite at: http://www.pca.state.mn.us/yrwc6a9 , listed under Tuesday, December 23, 2014 (on the Archived Public Notices page afte r January 21, 2015). After its issuance, the permit will be submitted to EPA for inclusion into Minnesota’s SIP to replace the Order. Unt il the time that the EPA accepts Permit No. 03700011- 012 into the SIP, the Order is in full effect and FHR must comply with all aspects of it. Once EPA approves Permit No. 03700011-012 into t he SIP, the MPCA will revoke the Order and the joint Title I/Title V permit will become t he applicable enforcement document.

Inver Hills’ permit incorporates Title I requi rements which are included in Minnesota’s SIP and w ere found necessary to demonstrate compliance with the NAAQS for SO 2 

### . Title I conditions in Inver Hill’s Air Emission Perm it No. 03700015-003 are already included in Minnesota’s SIP. Under its Title I authority, the MPCA is revising the SIP conditions for this facili ty and will be formally requesting that
the EPA amend Minnesota’s SIP to include the new and revised Title I S IP conditions in Inver Hill’s Air Emissions Permit No. 03700015- 004, which will serve as a joint Title I SIP/Title V document. These Title I conditions do not expire . Permit No. 03700015-004 was placed on public notice from June 2, 2014 to July 1, 2014 an d the MPCA subsequently issued the permit which is the enfor ceable document for Inver Hills. The permit can be viewed on the MPCA’ s website at http://www.pca.state.mn.us/index.php/view-document. html?gid=21400

.

The proposed SIP revision is now available for public comment.

Background. Title I of the Clean Air Act delegates to the stat es the authority to manage an air quality program a nd requires attainment of the NAAQS as promulgated by the EPA. Both the F HR facility and the Inver Hills facility are locate d in the Rosemount/Pine Bend area
of the Twin Cities SO 2 

### maintenance area for the three-hour, 24-hour, and annual SO 2 

### NAAQS. A maintenance area is an area which at one time failed to meet one or more NAAQS, but is now in compli ance and has an EPA-approved plan for continued attainment. Bo th FHR and Inver Hills are subject to facility-specific Ti tle I SIP conditions to ensure continued attainment of the SO 2 

### NAAQS.

Purpose of the SIP revision. This SIP revision is intended to incorporate new and rev ised Title I conditions for FHR, replace the existing Order, and incorporate all Title I SIP condit ions into Permit No. 03700011-012, which will serve as a joint Title I/Title V 

# Official Notices

### (Cite 39 SR 1099) Minnesota State Register , TUESDAY 20 January 2015 Page 1099

document. The primary purpose of this SIP revision is to add a new process to enable the removal and recovery of more sulfur from fuel produced at the refinery. This new process will al low FHR to produce gasoline that meets the EPA’s Ti er 3 gasoline sulfur standard, which is designed to improve ambient air quality. Changes t o FHR’s SIP conditions that are included in Permit No. 0 3700011-012 as proposed
are as follows:

· Installation of a new process to convert gas-contai ning sulfur and nitrogen into a stable, non-hazardous, aqueous liquid fertilizer, ammonium thiosulfate (ATS), which will result in a new SO 2 

### emission point.

· Changes to the fuel gas sulfur monitoring requ irements for the 45 unit mix drum to add direct mon itoring of fuel gas total sulfur as an additional monitoring option to the current requirement to monitor at a rep resentative stack for sulfur dioxide emissions. Remove outdated requirements for monitoring H 2 

### S.

· Incorporate new, more restrictive language refl ecting FHR’s current flaring policy, which allows for fl aring only in the event
of malfunction.

· Assorted updates that serve to clarify the requirem ents of the Order by removing completed requirements a nd placeholders.

This SIP revision also incorporates revised Ti tle I requirements for Inver Hills, held in Permit No. 03700015-004 which serves as a joint Title I/Title V document, into Minnesota’s SIP. The changes t o Inver Hill’s SIP conditions are as follows:

· Residual fuel oil has been removed as an allow able fuel type in accordance with the revised SIP.

· Removed SIP limits that were terminated on the date that EPA a pproved the revision to the previous SIP.

There are no SIP-relevant construction changes bei ng made to the Inver Hills facility and therefore thi s proposed SIP revision does not authorize any new operations or emission units at t hat facility.

Air dispersion modeling has been conducted to ve rify that the changes proposed in this notice will not have an adverse impact on compliance with the NAAQS for SO 2

## Attachment 5: Completeness Review

A. Administrative Materials (40 CFR pt. 51, Appendix V, Par t 2.1)

The EPA’s Criteria for Determining the Completeness of Plan Submittals, published at 40 CFR part 51, Appendix V, requires states to provide the basic documents that show that the State has properly followed the administrative requirements called for by the CAA for the adoption of S IPs. The requirements, and how this SIP revision comp lies with these requirements, are discussed here:

1) Formal Letter of Submittal:

“A formal letter of submittal from the Governor or hi s designee, requesting EPA approval of the plan or revision thereof.”

Attached to this SIP revision request is a formal letter o f submittal from the MPCA Commissioner, John Linc St ine, to the EPA Region V Administrator, Susan Hedman. The office of the Commissioner of the MPCA is statutorily created in Minnesota Statute § 116.03, subd. 1 (a). The Commissio ner is appointed by the Governor, and the duties of t he position include acting as the state agent to “apply for, receive, and disburse federal funds made available to the state by federal law or rule and regulations promulgated thereunder for an y purpose related to the power and duties of the MPCA or the Commissioner. The Commissioner shall comply with any and all requirements of such federal law or such rules and regulations promulgated thereunder to facilitate applicat ion for, receipt, and disbursement of such funds.” Min n. Stat. § 116.03 subd. 3.

2) Evidence of State Adoption of Plan and Issuance of Ord ers in Final Form

“Evidence that the State has adopted the plan in the State code or body of regulations; or issued the permit, order, consent agreement (hereaf ter ‘document’) in final fo rm. That evidence shall include the date of adoption or fin al issuance as well as the effective date of the plan, if different from the adoption/issuan ce date.”

Attachment 1 contains the joint Title I/Title V permit iss ued to Xcel Inver Hills, which consists of Air Emissio n Permit No.
03700015-004. The joint Title I/Title V document includes relevant SIP conditions, labeled “ Title I Condition: SIP for SO2 NAAQS, 40 CFR pt. 50 ”. This Air Emission Permit became effective as soon as it was signed. All Title I SIP conditions are non-expiring.

3) Legal Authority Documentation:

“Evidence that the State has the necessary legal authority under State law to adopt and implement the plan.”

This SIP revision request is an update to MPCA’s Pine Bend SO 2 

## SIP. This SIP was submitted by the MPCA in July 1992 and approved by EPA in the Federal Register on September 9 , 1994. EPA’s approval of a redesignation request for th e area was published on May 31, 1995 (60 FR 28339). Attachment C of the initial submittal documents MPCA’s legal authority to submit SIP revisions and to issue, modify, and revoke permits, as well as to enforce those permits.

On May 2, 1995, EPA approved MPCA’s revised operating permit program as a SIP revision (60 FR 21447). MPCA submitted the operating permit program for inclusion in the SIP in part so that permits issued under the pro gram could be considered federally enforceable vehicles for impo sing emissions limitations on culpable sources located in nonattainment areas.

EPA’s conclusion that MPCA has the authority to issue permits with non-ex piring Title I SIP conditions in order to replace Administrative Orders has been further documented in an A pril 4, 1997 letter from Michael Sandusky of the MPCA to David Kee of EPA Region 5, a July 3, 1997 letter from D avid Kee of EPA Region 5 to Michael Sandusky of the MPC A and in

## a June 15, 2006 letter from Jay Bortzer of EPA Region 5 to David Thornton of the MPCA. Copies of these letter s have been submitted with previous SIP revisions.

4) Compliance with State Procedures:

“Evidence that the state followed all of the procedural requirements of the State’s laws and constitution in conducting and completing the adoption/ issuance of the plan.”

MPCA complied with all relevant state procedures for is suing the permit as well as the SIP revision, includ ing a public notice period and the opportunity to request a hearing.

5) Public Notice:

“Evidence that public notice was given of the proposed c hange consistent with the procedure s approved by the EPA, including the date of the publ ication of the notice.”

The public notice for the SIP revision was published in the State Register on January 20, 2015 with the publ ic comment period commencing on January 20, 2015 and ending on Fe bruary 20, 2015. During the public comment period, a copy of the SIP revision was made available at the MPCA office loc ated in St. Paul and on the MPCA’s website. A copy of the public notice is attached (Attachment 4).

The public notice for the joint Title I/Title V permit was published in South St. Paul’s Southwest Review newspaper on June 1, 2014 as well as on the MPCA website, with the public comment period commencing on June 2, 2014 an d ending on July 1, 2014. During the public comment period, a copy of t he permit was made available on the MPCA’s website and at the MPCA offices in St. Paul. A copy of the public notice is attached (Attachment 4).

6) Public Hearing Certification:

“Certification that public hearing(s) were held in accord ance with the info rmation provided in the public notice and the State’s laws and con stitution, if applicable.”

The public notice states: “ A public information meeting will only be held if one is requested by 4:30 p.m. on February 20, 2015. If such a meeting is requested, it will be held on February 26, 2015 at 1:30 p.m. at the MPCA St. Paul Office, 520 Lafayette Road North, St. Paul, Minnesota 55155-4194.

No public meeting was requested.

7) Public Comments and State Response:

“Compilation of the public comments and State’s response thereto.”

No public comments on the SIP were received.

B. Technical Support:

1) Pollutants Regulated:

“Identification of all regulated pollutants affect by the pla n.”

## The regulated pollutant subject to this SIP revision is sulfur dioxide (SO 2 

## ).

2) Source Identification

“Identification of the locations of affected sources including the EPA attainment/nonattainment designation of the locations and the state of the Attainment Plan for the affected area(s).”

The affected source within the Pine Bend portion of th e AQCR131/Twin Cities SO 2 

## maintenance area is Northern States Power Company’s Xcel Energy

– Inver Hills Generating Plant. Further information on the facility is included in the attached Technical Support Document (Attachment 1).

3) Emissions Quantification:

“Quantification of the changes in the plan; allowable emissions from the aff ected sources; estimates of changes in current actual emissio ns from affected sources or, where appropriate, quantification of the changes in actual e missions through calculations of the differences between certain baseline levels and allowable emissions anticipated as a result of the revision.”

The changes allowed in this SIP revision call require that Inver Hills use a lower-sulfur content liquid fuel . This change will result in a reduction of SO 2 

## emissions from this facility. Details can on the SIP changes can be found in the Background Document.

4) NAAQS Protections:

“The State’s demonstration that the NAAQS, prevention of si gnificant deterioration increments, reasonable further progress demonstration, an d visibility, as applicable, are protected if the plan is approved and implemented.”

The changes allowed in this SIP revision call require that Inver Hills use a lower-sulfur content liquid fuel . This change will result in a reduction of SO 2 

## emissions from this facility. Details can on the SIP changes can be found in the Background Document. The proposed changes at the facil ity will help to maintain 3-hour, 24-hour, and annual SO 2 

## NAAQS and will not negatively impact the 1-hour standard.

5) Modeling Information

“Modeling information required to support the proposed revision, including input data, output data, models used, justification of the model sele ctions, ambient monitoring data used, meteorological data used, justification for use of off-site data (where used), modes of models used, assumptions, and other information relevant to the determination of adequacy of the modeling analysis.”

Because the revision to Inver Hills’ SIP will reduce SO 2 

## emissions from the facility, air dispersion modeling was not conducted.

6) Continuous Emission Reduction

“Evidence, where necessary, that emission limitations ar e based on continuous emission reduction technology.”

These requirements are addressed in the permit and joint Title I/Title V document issued to the source (Attach ment 1).

## 7) Emission Level Assurance

“Evidence that the plan contains emission limitations, w ork practice standards and recordkeeping/requirements, where necessary, to ensur e emissions levels.”

These requirements are addressed in the permit and joint Title I/Title V document issued to the source (Attach ment 1).

8) Compliance/Enforcement

“Compliance and enforcement strate gies, including how compliance will be determined in practice.”

These requirements are addressed in the permit and joint Title I/Title V document issued to the source (Attach ment 1).

9) Special Economic and Technological Justifications:

“Special economi c and technological justifications required by any applicab le EPA policies, or an explanation of why such justifications a re not necessary.”

Does not apply to this SIP submittal.
